If there is a crack in the heat exchanger as has been suggested, you can get a battery operated CO (carbon monoxide) detector which will beep if you have CO leaking from the combustion chamber into the RV. It is unlikely a crack is your problem.

If that passage is clogged or even partly obstructed, the furnace has a "sail switch" that monitors airflow and prevents the burner from igniting if the air flow is obstructed. That is not your problem.
